This can improve the photoelectric conversion efficiency of silicon wafers, reduce the reflection and scattering of light on the surface of silicon wafers, and thus enhance the performance of solar panels.

(5) Leather processing
Oxalic acid can be used as a tanning agent in leather processing. It can penetrate into leather fibers and react chemically with collagen in leather to form a stable cross-linked structure, making leather more stable and preventing decay and hardening. Leather tanned with oxalic acid has good softness, toughness, and wear resistance, which can meet the production needs of different leather products.

(6) Rust removal function
Oxalic acid has rust removal function and can be used for rust removal. Oxalic aci can combine with metal ions and react chemically with rust (mainly composed of iron oxide) to produce soluble iron oxalate, thereby removing rust from the metal surface. However, caution should be exercised when using oxalic aci. Oxalic aci has strong corrosiveness to stainless steel, and high concentrations of oxalic aci can easily corrode hands. The resulting acid oxalate has a high solubility but some toxicity.

(1) Drug manufacturing
Oxalic aci is widely used in the pharmaceutical field and can be used to manufacture drugs such as streptomycin, oxytetracycline, tetracycline, streptomycin, borneol, vitamin B12, phenobarbital, etc. In the process of drug synthesis, oxalic aci can act as a reactant or catalyst, participate in chemical reactions, and promote the synthesis and conversion of drug molecules. For example, in the synthesis of streptomycin, oxalic acid can react with certain intermediates to form precursor compounds of streptomycin, which are further processed and purified to obtain the final drug product.

(2) Acid resistance and pain relief
Oxalic acid has an antaci effect, which can inhibit the level of uric aci in the human body, help treat hyperuricemia and gout, and alleviate related symptoms. It can bind with uric aci in the body, reduce the concentration of uric aci, and decrease its deposition in joints and kidneys, thereby relieving pain and inflammation caused by gout. In addition, oxalic aci also has analgesic effects and can alleviate pain symptoms caused by diseases in patients. However, its specific analgesic mechanism is not fully understood and may be related to regulating neurotransmitter release or affecting inflammatory responses.

(3) Promote calcium absorption
Oxalic acid powder can combine with calcium to form easily absorbable calcium oxalate, thereby increasing the absorption rate of calcium and improving bone health. Under certain conditions, the combination of oxalic aci and calcium can form a stable oxalate calcium complex. This complex has relatively high solubility and absorption rate in the intestine, which can provide more calcium elements for the human body, help maintain normal bone growth and development, and prevent bone diseases such as osteoporosis.

(4) Improving cardiovascular health
Oxalic aci can regulate lipid metabolism, reduce cholesterol accumulation in the body, and help lower the incidence of cardiovascular disease. It can affect the synthesis, decomposition and transport of lipids in the body, reduce the level of low-density lipoprotein cholesterol (LDL-C) in the blood, and increase the level of high-density lipoprotein cholesterol (HDL-C), thus improving the blood lipid profile, reducing the risk of atherosclerosis, and protecting the health of the cardiovascular system.

(1) Chemical reagents
Oxalic acid is an important chemical reagent in the laboratory, commonly used in the preparation of other chemicals such as oxalate esters, oxalate anhydrides, diethyl oxalate, sodium oxalate, etc. In organic synthesis experiments, oxalic aci can undergo esterification reactions with other alcohol compounds to generate various oxalate esters, which have wide applications in fields such as fragrances, coatings, plastics, etc. In addition, oxalic aci can also be used to prepare oxalic anhydride.

Which is an important organic intermediate that can be used to synthesize various organic compounds.

(2) Participate in chemical reactions
Oxalic acid can serve as a reducing agent in the laboratory and participate in various chemical reactions. For example, it can cause the acidic potassium permanganate solution to fade and reduce it to divalent manganese ions, which is used as a method for determining the concentration of potassium permanganate in quantitative analysis. In chemical analysis, oxalic aci can also be used to precipitate metal ions such as calcium and magnesium, forming insoluble oxalate precipitates with these metal ions to achieve separation and determination of metal ions.

(1) Dealing with heavy metal pollution
Oxalic aci can combine with heavy metal ions to form soluble oxalate salts, which helps to remove heavy metal pollution. In industrial wastewater treatment, if the wastewater contains heavy metal ions such as lead, mercury, cadmium, etc., an appropriate amount of oxalic aci can be added to react the heavy metal ions with oxalic aci to form soluble oxalate.

Then, the heavy metal ions can be removed from the wastewater through precipitation, filtration, and other methods to achieve the goal of purifying the wastewater.

(2) Treating wastewater and exhaust gas
Oxalic acid powder can be used for the treatment of wastewater and exhaust gas, reducing the emission of pollutants. In wastewater treatment, oxalic acid can adjust the pH value of the wastewater to achieve suitable treatment conditions, and can also react chemically with certain organic pollutants in the wastewater to decompose them into harmless substances. In exhaust gas treatment, oxalic acid can absorb certain harmful gases such as sulfur dioxide, reducing the pollution of exhaust gas to the atmosphere.

(1) Other fieldsFood processing (small application)
A small amount of oxalic aci can be used in food processing, such as bleaching or preservation, but the dosage needs to be strictly controlled. In terms of food bleaching, oxalic aci can remove pigments and impurities on the surface of food, improving the appearance quality of food. In terms of food preservation, oxalic aci has a certain antibacterial effect, which can inhibit the growth and reproduction of certain microorganisms and extend the shelf life of food.

However, due to the toxicity of oxalic aci to the human body, its use in food processing is strictly restricted and regulated.

(2) Plant extraction process
Partial plant extraction processes utilize oxalic aci to dissolve impurities and purify target components. During the extraction process of plant active ingredients, plants often contain impurities such as cellulose, hemicellulose, lignin, etc. Oxalic acid can undergo chemical reactions with these impurities, causing them to dissolve in the extraction solvent, thereby achieving the separation of target components from impurities, improving the purity and extraction efficiency of target components.
